Trevor Bayliss admitted he was at a loss to explain England's shambolic collapse to 58 all out inside the first session of this opening Test against New Zealand.

This may have been the first day-night Test in this country but shocking batting by Joe Root's team in bright sunlight ensured there was daylight between the teams by the time the hosts reached the close on 175 for three, a lead of 117.

England were blown away in just 94 minutes as Trent Boult took a career-best 6-32 and Tim Southee followed up with four wickets. Asked to explain the batting horror show, England's coach said: "I can't, it was a very poor effort - it wasn't good enough. I thought New Zealand bowled extremely well and we batted equally as badly."

Bayliss also admitted he was embarrassed by the collapse, saying: "Certainly, and I probably wasn't the only one in the England changing room either."

England, humbled 4-0 in Australia as they lost the Ashes earlier this winter, have failed to win any of their past 11 overseas Tests and will surely not prevail in this one either.

As coach, Bayliss knows he is ultimately responsible for results and the Australian admitted: "Certainly, it hurts from that point of view. That'll be up to you guys I suppose (whether he is sacked), what you want to write. But, look, whenever you don't do well it does hurt. So all we can do is take it on the chin, work out what we can do better and go back and work as hard as we can at it."

Bayliss was also frank when questioned as to whether this performance represented rock bottom for England during what has been a nightmare Test winter so far.

"On the scoreboard certainly - 58, that's obviously well below par," he said. "I thought we made a lot of mistakes.

"Is it a mental approach, is it something in our preparation? Are we good enough at working out how to play when we do lose wickets?

"Someone sneezes and the rest of the guys catch a cold don't they? Everyone was making the same type of mistakes."
